Abstract

In this study, a new jacket-type breakwater was proposed for the economical construction of breakwaters in deep-sea ports. This breakwater consists of water chambers with two inclined walls and a submerged horizontal plate. In order to reinforce the breakwater structure, the inclined support piles were adopted instead of vertical piles. Accordingly, the inclined walls were used as front and rear curtain walls. Piston mode wave resonance can be employed in the water chamber to effectively dissipate incoming waves by the generation of separated flows and the resultant vortex flows around the front curtain wall. The performance of the proposed breakwater was examined from the theoretical and experimental viewpoints. Considering the experimental results, we decided to construct an economical water-chamber-type breakwater on the adopted site.
